3M™ Scotch-Weld™ Structural Adhesives
Load-bearing formulations for
metals, rubber, glass and more.
6
As an alternative to mechanical or fusion
fastening, the reasons for Scotch-Weld
Adhesives are many: greater design latitude,
cleaner lines, material substitution, less
machining, lighter weight, more durability,
and often less cost.
To meet application and end-use
requirements you can select from one-part
heat-curing epoxies, and two-part roomtemperature curing epoxies, acrylics and
urethanes. There are formulations for
bonding steel, aluminum, copper, low
surface energy plastics, rubber, glass,
wood, masonry and more.
7
Whatever properties you need– durable
adhesion, flexibility, creep resistance,
heat and environmental resistance,
void-filling—you’ll likely find a
Scotch-Weld product to meet your
requirements and expectations.

3M has long been recognized as a pioneer in structural strength adhesives. But to meet end use
performance requirements doesn’t just mean providing the right chemical formula. Which is why
3M also develops dispensing systems to facilitate production in low and high volume assembly.
Many two-part 3M formulations are available in Duo-Pak cartridges for dispensing with a manual
or pneumatic 3M ™ EPX™ Applicator.

Refrigerant coil – 3M ™ Scotch-Weld™ Epoxy
Adhesive 2214 bonds and seals coils with overlap
shear strength of 4500 psi. One part eliminates
metering and mixing.
Porch railing – 3M™ Scotch-Weld™ Structural
Plastic Adhesive DP- 8005 bonds unique thermoplastic composite in assembly of hollow railings
that are stiffer than wood.
Retail store display columns – To maintain the
quality wood-like appearance, 3M ™ Scotch-Weld ™
Structural Plastic Adhesive DP-8005 eliminates
screws, nails, and related surface finishing in
assembly of plastic composite components.

Bicycle frame assembly – 3M ™ Scotch-Weld™
Epoxy Adhesive DP-420 bonds steel couplings
into aluminum tubing of the frame. Couplings
are threaded for easy assembly and disassembly.
The toughened epoxy bonds for the long run in
high stress areas.
15
Bonding magnets to steel rotor – Bonds made
with 2-part 3M ™ Scotch-Weld™ Epoxy Adhesive
DP-460 cure at room temperature and reach 4500
psi in overlap shear strength. Void-filling properties
secure loose fitting surfaces.

CPS
A primer for film and liquid adhesives in those applications where it is desired to
obtain improved metal and glass adhesion or improved resistance to environmental
exposure with epoxy and urethane adhesives. It can help simplify production
scheduling by protecting the cleaned surfaces until the bonding operations can be
completed and imparts improved corrosion protection to metal.
• 1:1 mix ratio 2-part
epoxy primer
• 8 hour potlife
• Brush, spray or dip application

CPS
It is a two-part chemically curing, corrosion resistant primer to improve adhesion
of urethanes and epoxies to many metals as well as offering increased corrosion
protection. It cures at room temperature and has excellent adhesion to many metals.
